What exactly messes up an ODST coop save? (2009 issue,)

[ColinDJPat]

~~~Pls forgive my bad explanation of the issue.~~~
I remember having issues on ODST on 360, and I know it has the same issue in MCC, where you'll continue the game having beaten for example 3 missions, but when you get sent back to Mombassa Streets, the game thinks you haven't played the first mission, and sends you looking for the "clue" that starts mission 1.
I think it happened to single player too, but coop was more finicky.

Also, does starting a mission in a different campaign while I have an ODST save overwrite my ODST save?

I'd like to play the game w my partner but when I suggested getting some snacks and marathoning the game to avoid losing our save, they seemed completely turned off of ODST entirely.
:( I just want to share one of my fav games with them

Same happened to me. You have to select the rally point for each clue from the menu, manually. Then you'll be able to continue without starting over again.

I find it works better when playing coop campaign started from level select, rather than the playlist. For me and my roommate it only saved our stuff in Mombasa streets (weapons, mongooses etc) from level select. Playlist started us fresh every time we got back to streets.

ooooooooh ♥♥♥♥ I didnt realize they added that, so if we lose the saves we can still continue. Those rally points weren't selectable on 360 I think, so this will kinda fix it.
